She hasn't grown much really... I chop up worms and mix in tilapia and shrimp in the juices of the worms. Blood, guts, and all... Seems gross but this is the only way I've been able to get her to eat anything but worms...
I have a new food I am going to try with my picky male - Repashy's Meat Pie Fish Formula....some of the pups from the last litter of the superspot (5 weeks old now) are eating it like crazy! If it works I will let you know give you some!
Your right! this is a mini Marble. She needs to be 12" disc to breed though, 9"-10" is a full grown male, my mini marble pair have done the business and I am now waiting for pups, Mom is 12" and looking very big for her first time.
Imported some of these from the wild 3 years ago, 2 females arrived gravid and dropped pups in the tank soon after, both females were 12" disc and the pups were tiny...3.5 inches but fully developed, just what you would expect from these smaller locality Stingrays.
Sorry I don't! It was a while ago, I could have taken some at the time but have no idea where they would be.
From what I can make out these Marbles grow a little larger than Hystrix, the largest female I have personally seen was approx 16", males between 8-10" seems to be the norm, females reproduce regularly at 12" disc size. I currently have my mini Marbles in with my larger pair of Marbles, the size difference is ridiculous!! My largest female Hystrix past on a few years ago now, I had had her over 10 years and she had a 15" disc, the father was 10".
